Mice in oven 🥲

How do I keep them from getting in my oven when the gaps on either side are big enough for them to run through? Does anyone have any DIY ideas on kinda framing the range in? Our oven is located in a corner so there's big spaces where the cabinets end but the countertop continues. We live on a farm and we have 3 cats that pull their wight. Pics of ways you guys have closed up the gaps between the cabinets and appliances would be appreciated! I've been sealing up holes as I find them. Essential oils only deter them for so long.
